Linearly-rising part of the

The time, A t, required for the temperature of 2 cm of the substance charged in the draft cell, into which air is supplied, and subjected to the adiabatic oxidatively-heating test started from a below about 180 °C to increase by the definite value of AToi 1.25 K from the corresponding standard temperature is determined on the linearly-rising part of the oxidatively-heating process or curve of the substance. 

STM-measurements of the reversed process (1 x 1) (,/3 x, /3)R30° (peak Bi) clearly show that the terraces are preferential (hole) nucleation sites, and that the new phase grows linearly with time. Increasing the substrate step density modifies this mechanism the maxima of the rising part of the corresponding current transients appear distorted. Similar trends were observed for the desorption process around A2. Unfortunately, the STM and chronoamperomet-ric experiments did not yet allow the derivation of a quantitative correlation between step density and the elementary steps of 2D phase formation of Cu-UPD. 

An interesting detail is that in logarithmic proportions the middle, rising part of the dependence is practically linear, meaning that there is a certain range of bias currents where specific detectivily increases exponentially. In real situations this is significantly impaired by the existence of 1/f noise. 

Weak acid with a strong base. In the titration of a weak acid with a strong base, the shape of the curve will depend upon the concentration and the dissociation constant Ka of the acid. Thus in the neutralisation of acetic acid (Ka— 1.8 x 10-5) with sodium hydroxide solution, the salt (sodium acetate) which is formed during the first part of the titration tends to repress the ionisation of the acetic acid still present so that its conductance decreases. The rising salt concentration will, however, tend to produce an increase in conductance. In consequence of these opposing influences the titration curves may have minima, the position of which will depend upon the concentration and upon the strength of the weak acid. As the titration proceeds, a somewhat indefinite break will occur at the end point, and the graph will become linear after all the acid has been neutralised. Some curves for acetic acid-sodium hydroxide titrations are shown in Fig. 13.2(h) clearly it is not possible to fix an accurate end point. 

Excitation-wavelength-dependent emission polarization studies indicate the presence of an overlapping xy polarized transition in the bluer part of the 290-315-nm range, as indicated in Fig. 5. The combination of static absorption, time-resolved emission, and emission quantum yield measurements suggests that the emitting state has the same polarization (z axis, linear), but is not the same state as that giving rise to the 362-nm absorption peak. These assignments for the 3.5-nm particles are summarized in Fig. 5. 

Non-linearity in amplifiers or other parts of the system gives rise to intermodulation distortion [Sinclair, 1989],... 

Eq. (1) is used to find the d-band width (6.5 eV) once the other parameters of the band shape are determined. Similarly, Eq. (2) is used to determine the s-band width (12.9 eV) of a free-electron density of states symmetric in energy about the middle of the band. The d-band density of states, Nj(E). rises sharply at the lower band edge to about 1.5 states/eV atom then falls off to 0.47 states/eV atom near the middle. With the general shape of Nj. (E) and Ns(E) given, the critical magnitude of Nd( q ), the chemical potential in d-orbital, is determined from the observed linear part of the low-temperature specific heat as follows ... 

Single-screw Pump with Inner Recycle A constant channel-depth single-screw pump with a linearly rising pressure has a hollow shaft, as shown in the accomapny-ing figure, connected to the channel such that part of the flow is recycled. Assuming isothermal Newtonian flow (a) derive and expression for the flow rate of the extruder, and (b) for the recycle rate. 

Accordingly, the modifications to the KS operator are twofold (i) a static contribution through the static multipole moments (here charges) of the solvent molecules and (ii) a dynamical contribution which depends linearly on the electronic polarizability of the environment and also depends on the electronic density of the QM region. Due to the latter fact we need within each SCF iteration to update the DFT/MM part of the KS operator with the set of induced dipole moments determined from Eq. (13-29). We emphasize that it is the dynamical contribution that gives rise to polarization of the MM subsystem by the QM subsystem. 

Within 14 min the resistance of a layer with AZ = 1.5 cm increases from 30 to 100 kf2 (curve 1) and the rise is practically linear. This corresponds to an increase in the expansion ratio from 6 103 to 20 103. Even during the first minute the expansion ratio increases about 100 times. This part of the Rf(t) dependence corresponds to the reduction in the foam liquid content and to the increase in the foam capillary pressure without a change in the foam layer thickness, which is confirmed also by the direct observation of the foam state after the centrifuge is stopped. Further on the resistance sharply increases (part A B B of curve 1) due to the decay of the foam column. Within minutes the resistance increases to several Mf2 and... 

The theory predicts that in both cases the threshold level rises linearly with stimulation in the first part of the curve and keeps rising until the threshold level equals the level of stimulation. Since we still use Stevens law which has now taken a time-dependent form I - k (S-S ), we may predict that the higher concentration will be perceived...
